SPECIFICATION forming part of Letters Patent No. 592,729, dated0ctober.26,"-1897.

A plication filed December 10, laps. Serial No. 615,195. (No model.)

To all whom it may concern:

Be it known that I, GEORGE GODDU, residing in Winchester, in the countyof Middlesex and State of Massachusetts, have invented an Improvement inNail-Making Machines, of which the following description, in connectionwith the accompanying drawings, is a specification, like letters andfigures on the drawings representing like parts.

This invention relates to an apparatus for producing string-nails from asubstantially flat ductile ribbon or band of metal, whereby duplicatestrips or lengths of string-nails may be made at one operation and in acontinuous manner, so that each string nail strip consists of aplurality of connected headed and pointed nails having tapering sidesextended from the points to the heads and so that the ribbon or band isout without loss of metal and the string-nail formed so as to retain theoriginal ductility of the band. a

In accordance with this invention the ribbon or band, which is to beformed into duplicate nail-strips comprising connected headed andpointed tapering nails of uniform length, is cut longitudinally andtransversely intermediate of its sides, the longitudinal cuts beinginclined with relation to the sides of the ribbon or band and thetransversecuts extending substantially at right angles to the sides ofthe ribbon or band and made of less length than the Width of the saidribbonor band, so as to leave uncut portions of metal at opposite endsof the said transverse cuts, which uncut portions form the points of oneset of nails and a portion of the heads of a contiguous set of nails, sothat duplicate nailstrips of connected headed and pointed nails areformed at one operation without waste of metal and without decreasing inthe .nailstrips thus formed the ductility of the original ribbon orband.

The ribbon or band may and preferably will be cut longitudinally andtransversely, as above stated, by means of rotatable cuttingdisks orcircular dies, between which the said ribbon or band is fed and whichare arranged with the inner side of one disk overlapping the outer sideof the other disk to an extent or distance substantially equally-to thelength ofthe transverse cuts in the ribbon or band.

The'circular disks or dies are provided on their contiguous or adjacentoverlapping faces at their circumferential edges with a plurality ofconnected orcontiguous shallow recesses, preferably tapering andconstituting the dies proper,'each of which is substantially triangularin shape on the periphery of the said disks and tapers or inclinesradially from the said periphery toward the side of the disk.

The edges of the recess in the periphery of the cutting-disks constitutethe cutting edges of the dies, and the triangularedges on the peripheryof one disk extend in an opposite direction from the triangular cuttingedges of the cooperating disk, so that the said edges may register orcoincidewhen the circular dies or disks are rotated in oppositedirections.

The inclined cutting edges of the dies are made of a length equal to thelength of the tapered side of each connected'nail, and in order that theconnected headed and pointed tapering nails may be of uniform length thecircular disks are made of the proper diameter to'obtain acircumferential length divisible by the desired length of nail, so thatthe entire circumference of the circular disk may be provided with dieshaving in olined cutting edges of uniform length, and as a result allthe nails cut in one revolution of the disks are of uniform length,which is especially desirable and advantageous when the stringnailstrips are employed in the manufacture of boots and shoes.

The ribbon or band on its passage to the revolving dies is passedthrough a guide of a novel construction, as will be described,which isextended to substantially the p oint where the said'dies out the ribbonor band, and after being acted upon by the revolving cutters thestring-nails thus formed are passed between suitable straighteningdevices, preferably rolls, and are then carried to separate reels, uponwhich they are wound or coiled. The nail-strips, after leaving thestraighteningrolls, are separated and are carried through a strip-guideortraverse, to which motion is applied, as will be described, so as tolay the string-nails upon the reels as the latter are revolved, as willbe described.

These and other features of this invention will be pointed out in theclaims at the end of this specification.

In accordance with this invention a ribbon or band A, substantially flatand of uniform thickness throughout its length, having parallel sides 23 and preferably of a width sufficient to be cut into two strips A A inone continuous operation and without loss of metal, is subjected to thecutting action of suitable dies A A of novel construction, as will bedescribed, which are mounted upon shafts a a, (see Fig. 2,) havingbearings in a suitable framework, herein shown as consisting of twosleeves or cylindrical hubs a a through which the shafts a a areextended and in which the said shafts have a substantially long bearing,the said shafts fitting the said sleeves or hubs, so as to runsubstantially tight therein. The bearing a is secured to or forms partof an upright web a, erected upon a table or platform a, supported uponsuitable legs a, as herein represented, and the bearing a in the presentinstance is lo cated above the bearin g a and secured to and supportedby the bearing (1 as will now be described.

Referring to Figs. 3 and 4, the bearing a on its opposite sides and atopposite ends thereof is provided with two sets of laterallyprojectinglugs or cars (1 with which register like ears or projections a on thebearing a and the ears or laterally-projecting lugs a are adjustablyfastened to the lugs or ears a by means of bolts or screws a, extendedthrough suitable slots in the lugs or cars a and into suitably-threadedsockets in the lugs or ears (1 the lugs or cars a also having threadedholes through which are extended adj usting-bolts a which bear on theupper surface of the lugs or cars a The cuttingdisks A A are mounted onthe ends of the shafts a a, which project beyond one end of the bearingsa a and in the present instance the cutting-disks A A are rendered fastonto the shafts a a, so as to revolve therewith, by means of caps orwashers 61. fitted over the ends of the shafts a a and secured theretoby means of screws a a, which are tapped into the ends of the shafts aa, and which have their heads abutting against the ends of the caps orwashers a a. The shafts a at, as herein shown, are provided at one endof the bearings a a with annular flanges a a", between which and thenuts or Washers a 0. the cutting-disks A A are firmly clamped. Theshafts a CL are rotated in opposite directions by means of a gear a 011the shaft a (see Fig. 4) meshing with a gear (1 on the shaft a, the saidgears being adj ustably fastened to their shafts, as by screws or bolts60 e extended through split hubs e a of the said gears and throughelongated slots in the shafts, only one of said slots a being shown inFig. 13, the said bolts being provided with a head If and with a nut 11(See Fig. The shaft a in the present instance is represented as the mainshaft, and has mounted upon it driving-pulleys e (4 the shaft a havingits extreme end journalcd in a bearing-hub a, attached to asubstantially U-shaped bracket or arm a which in the present instance isrepresented as intogral with the table or platform a.

The cutting-disks A A are provided on their peripheries at theircircumferential edges with a plurality of connected or contiguousshallow recesses 12, constituting the dies proper, and each of the saidrecesses or dies is provided in the present instance with substantiallytriangular cutting edges, consisting of a substantially long inclinedcutting edge Z) and a shorter transverse cutting edge I), the inclinedcutting edge Z) extending y from one face of the cutting-disk A until itmeets the inner end of the transverse cutting edge which also extendsfrom the same face of the cutting-disk. The inclined cutting edge I) ofthe die I) on the cutting-disk A and the transverse cutting edge b ofthe said die extend in an opposite direction from corresponding cuttingedges of the dies Z) on the disk A and the disks A A are arranged ontheir respective shafts a a, so as to overlap one another a distancesubstantially equal to the length of the transverse cutting edges I), sothat in the revolution of the cutting-disks A A in opposite directionsthe cutting edges of the contiguous dies on the cutting-disk A willregister or coincide with the cutting edges feet a complete cut of theband A passed or cutting-disks A A it will be cut longitudinally andtransversely intermediate of its sides 2 3, so that the successivetransverse cuts leave on opposite sides of them uncut or connectedportions of the strip, which form, respectively, the point of. one nailand a portion of the head of a contiguous nail, and the inclined-cuttingedges of the dies 17 form a longitudinal cut in the band Aintermediateof its sides 2 3 and inclined with relation to the said sides, as shownin Fig. 9, to form in one operation the tapering sides of the two nails,which tapering sides extend from the head of one nail to the point ofthe next adj acent or contiguous nail, thereby permitting duplicatestring-nail strips A A to be formed from the band A without loss ofmetal.

In the present instance I have represented in the drawings each of thecutting-disks A A as provided with two sets of dies b at the oppositeedges or sides of the said disks, so that in case the cutting-edges ofone set of dies should become dulled the other set of dies may beutilized by transferring the cutting-disk A from the shaft a. to theshaft a and the cutting-disk A from the shaft a to the shaft'a. Inpractice the shaft 0. is adjustable radially with relation to the shafta by the adjusting-screws a (see Fig. 4,) so that the cutting-edges ofthe dies 1) on the disks A A may be brought substantially in contact orin such close proximity as will effed between them, and also to take upwear in the gears or a whereby the teeth of the said gears may engage,so as to obviate lost motion.

The shaft c is prevented from moving end-. wise by the flange a"abutting against one end of the bearing a and by the gear a abuttingagainst the opposite end of the said bearing, and to compensate for wearof the flange and one end of the bearing a and of the gear and theopposite end of said bearing the gear a is adjustably secured to theshaft on, as above described. The shaft a is confined against endwisemovement in a similar manner by the flange a and the gear a and wear iscompensated for by adjustably securing the said gear as above described.In this manner the cutting edges of the dies 5 on the cutting-disks A Aare kept in proper working position with relation to each other.

In order to secure the complete severance of the ribbon or band intoduplicate nailstrips, the said band is firmly held against movementclose up to the cutting point or edge of the dies, which may andpreferably will be accomplished by means of a guide for the band,preferably made as herein shown, (see Figs. 1, 4, l0, and 11,) andconsisting of a block or metal piece b having at its rear end an arm I),which is fastened to the lug or ear a as by a screw 5 extended through aslot 100 in the arm b normally covered by thfllange on the head of thesaid screw. The brook b is provided, as shown,

with a substantially flat upper face, having in it a longitudinal slot,channel, or guideway 41 of substantially the same area in cross-sectionas the band or ribbon, so as to form a bottom upon which the striprests, and upright side walls separated from each other substantiallythe width of the strip, so as to substantially engage the strip andprevent lateral movement of the latter with relation to the cuttingedges of the disks A A ,'and the front end of the said block is splitvertically and longitudinally for a portion of its length to formspring-fingers 42 43, which are drawn or 42 43 on their front under sideare curved or arc-shaped, as at 44, (see Figs. 1 and 11,) and ofsubstantially the same curvature as the cutting-disk A so that the endof the guide may extend substantially to the cuttingpoint of the twodisks. The guide 12 is provided with a cap 19 secured thereto by a screw19 and tapering on its upper surface toward its front end to confine theband in the guideway 41 up to substantially the cutting-point, as shownin Fig. 1.

clamped or drawn together by the screw 19 which is inserted through themnear their rear endsthat is, near the rear end of the longitudinal slotin the block b so as to leave or impart to the front end of the fingersa slight spring action, which permits the said fingers to yield slightlyin case of any slight irregularity in the width of the band'A, and theguideway 41 is preferably made slightly tapering from its rear towardits front or discharge end, which permits the band to be easily drawn bythe cutting-dies through the said guideway in case the said band shouldbe slightly wider in parts than the width of .theguideway between thefingers 42 43.

The cap b is fastened by the screw Z2 to the solid rear part of theguide-block b, so that the front end of the cap may yield or be liftedin case the band A should be of uneven thickness. The fingers 42 43 ofthe guideblock may be adjusted toward and from each other by means ofthe adjusting-screw b to enable bands or ribbons A of varying widths tobe presented properly to the cutting-dies,

with uniform sizes of nails.

The severed ribbon or band A may, and preferably will, be passed throughstraightening devices, shown as rolls Z9 6 One of the rolls, 12 isloosely mounted on a stud or arbor I), carried by an upright or bracket5 secured to the table a, as byabolt or screw b and the other roll, as19 is eccentrically mounted in a hub or sleeve Z)" on the bracket 13and, as shown, is provided with a handle b ,by which theeccentricallysupported shaft for the roll 12 may be turned in itsbearings so as to increase or decrease the pressure or binding effect ofthe rolls 19 12 on the stringnail strips cut by the dies of the disks AA In the passage of the ribbon or band A be- 'held together by a screw band the fingers The fingers 42 43 of the guideway are so that theduplicate nail-strips may be formed tween the cutting-disks A A thenail-strips A A are forced by the cutting action of the disks A A, oneabove and the other below a plane extended between and tangential to thecutting-disks, and these nail-strips. are again brought intosubstantially the same plane after they have passed beyond thecuttingdisks A A by the straightening-rolls h Z1 The nailstrips A Aformed as above described, may, and preferably will, be wound uponseparate reels 0 0, located 011 the opposite faces or sides of a tootheddisk or gear 0 and of a construction as will be described.

The gear 0 as herein shown, (see Fig. 12,) is composed of a rim 5 and across-bar 6, from which extends a hub '7, and the said rim is providedwith an annular side flange 8, e011- stituting the periphery of the reelC and with which cooperates a removable side composed of a ring or rim9, attached to a spider 10, detachably mounted on the hub 7, it beingsecured thereon by a nut 12. The rim 9 of the removable side of the reel0 is preferably provided with strengthening-ribs 13 on its outer sideand is further provided with radially-extcnded openings 14, with whichcooperate radial grooves or channels 15 in the side of the gear 0 topermit of the passage of a binding or tie wire under and about the coilof string-nails wound on the reel C, so that the coil may be easilyremoved from the periphery 8 of the said reel after the removal of theside 9.

The reel C is separate from the gear a and is provided with two sides,one of which is composed of the rim 14, spider 150, from which latterextends a hub 16, and an annular flange 17, integral with the rim 1%,the hub 16 being fitted loosely on a stud or pin 18, driven into the hub7 of the gear 0'' and extended beyond the hub 16, which has fittedloosely on it the removable side 20.

The side 20 is secured by means of a nut 21, engaging screw-threads onthe end of the hub 16, and the completed reel C is secured on the pin 18by a nut 22. The gear 0 and its attached reels (J O are supported by asubstantially semicircular arm (Z secured to a bracket c as by a bolt orscrew 01 the said bracket being secured to the table a as by a bolt orscrew The substantially semicircular arm (Z is provided with asubstantially central and longitudinal groove (Z (see Fig. 3,) intowhich extends the gear a.

The gear 0 is rotated, as herein shown, by means of a pinion 0 fast onashaft or arbor 0 having bearings, as herein shown, in a sleeve or hub c,secured to or forming part of the bracket 0 the said shaft having faston it a hub 0 with which cooperates a loose pulley 0, connected by abelt 0 to the pulley a on the main shaft a. The loose pulley c is heldin frictional but yielding engagement with the hub e by means of aspring 0 encircling the threaded end of the shaft 0 between the pulleysc and an adjusting-nut c", and by means of said nut the tension of thespring 0 may be regulated, as desired, to increase or decrease thefriction between the pulley c and hub This frictional construction ordevice constitutes an automatic tension regulator for the coils wound onthe reels. The shaft 0 is further provided, as herein shown, near itsopposite end with a worm d, (see Fig. 3,) which engages a worm-gear d,(see Figs. 2 and 5,) fast on a shaft or arbor 61 (see Fig. 5,) havingbearings in a hub or sleeve (1 secured to or forming part of the bracket0 The hearing sleeve or hub c, as shown 'in Fig. 3, is provided with anopening or slot 0 into which the worm-gear d extends to engage the wormd. The shaft d has secured to or forming part of it a heart-shaped camor eccentric d, provided with a rcentrant portion or notch (1 located atsubstantially the center of the shaft (1 and with which cooperates afinger or projection d" on a guide arm or lever d pivotally mounted, asat 61 (see Fig. 2,) to a depending lug or arm d 011 the curved arm orsupport d The fingerd on the lever d is held in engagement with theheart-shaped cam (Z by means of a spring al shown as fastened at one endto the lever (Z and at its other end to a pin d, extended from the arm 0(See Fig. 5.) The lever d is provided with a substantially horizontalarm d havingtwo sets of upright fingers, forming guides d d", which areproperly separated or spaced to cooperate with the reels 0 C and betweenwhich the nail-strips are carried on their passage to the said reels.

The operation of the machine herein shown may be briefly described asfollows: The sub stantially fiat ductile band or ribbon A, of anydesired length and of substantially uniform thickness throughout itslength, is passed through the guide if to the cutting-disks A A, and iscut longitudinally and transversely between its sides by the dies 1) onthe said disks as the latter are revolved, and after passing beyond thecutting-disks A A the duplicate nail-strips A A which are severed fromeach other but remain integral with or attached to the uncut ribbon orband A, pass between the rolls 11 12 and then through the guides (Z d"of the strip-carrier to the reels 0 C, upon which they are wound insuccessive layers by the traverse of the stripcarrier al Then the reels0 C are full, the machine is stopped and the coil on the reel C isremoved after being tied together as described and may be placeddirectly onto the reel of a nailing or other machine, as its nails pointin the proper direction for driving them. The coil on the reel 0' iswound reversely, and therefore this coil is unwound from the reel 0 andwound upon a similar reel, so as to properly position the points of thenail. By making the cutting-disks of a diameter which permits theircircumferential length to be divided by the length of nail desired theindividual nails oi the stringnails are made of uniform length.

By making the shafts a a longitudinally adjustable, as described, thecutting edges of the disks A A may be accurately positioned or alined soas to insure proper cutting of the band. So, also, by making the shaft aadjustable radially with relation to the shaft a the cutting-disks maybe adjusted so that their cutting-edges are properly positioned and theteeth of the gears a a kept in close mesh or contact. The automatictension device insures the string-nails being properly wound on theirreels, as it governs the rotation of the gear 0 and the reciprocation ofthe strip-guide C1 The guide 6 is made adjustable in a planesubstantially parallel to the axis of the shafts a a, sothat the saidguide may be properly positioned with relation to the cuttihg-dies.

The stringnail strip produced with the machine herein shown and in themanner herein described is not herein claimed, as it forms thesubject-matter of another application, Serial No. 582,519, filed by meMarch 10, 1896.

By reference to Fig. 1 it will be seen that the guide b has its guideway41 extended beyond a vertical line tangential to the cutting-disks andclose up to the dies which are cutting the ribbonor band, and by reasonof the guide being provided with a bottom upon which the ribbon restsand with upright side walls which embrace the sides or edges of theribbon or band the guide has imparted to it the function of a supportfor the ribbon or band on its bottom and sides, so as to obviate theribbon or band turning or curling up sidewise under the action .of thedisks A A which in no way support the ribbon or band. The liability ofthe ribbon or band to curl or twist sidewise, and thereby be improperlypresented to the cutting edges of the disks A A which would result inspoiling both of the string-nails, is increased if the cutting-dies ofone of the disks should be duller than the other.
